(i know can invert condition: if not <condition>: print 'after condition' -- way above?) the best way encapsulate in function , use return : def do_it(): open(path) f: print 'before condition' if <condition>: return print 'after condition'

this skaction: naarrechts = skaction.movetox(positionx , duration: 0.22) player.runaction(naarrechts) in duration of 0.22 sec not want action run: if cgrectintersectsrect(player.frame, car.frame){ player.position.x = car.position.x } what magic line of code can detect if first skaction running, or detect wether player in movement or not.. you can create class variable var playerisinaction = false set true after run action. change method can write completion code (after action ends) set bool false . it should : playerisinaction = true player.runaction(naarrechts, completion: {() in playerisinaction = false }) and check bool if cgrectintersectsrect(player.frame, car.frame) && playerisinaction == false { //code }

i new java , container can use hold strings not empty , have them sorted. so far, have been using arraylist, seems bit limited case. thanks use treeset or treemap , depending on requirements. both collections accept unique elements , keep them sorted.

i trying load data allegro graph server , 1 of parameters --with-indices . can explain about? i have read entire allegro graph documentation , mentions indices can spogi , sopgi , etc, not mention about. please explain precisely. (i not asking full-forms of spogi , sopgi , etc. want exact meaning.) your triple store contains triples spo (subject, predicate, object). query against graph stored may have traverse lot of graph find nodes match query. allegrograph can store indices make traversal faster: finding predicates match first, example, , subject , object nodes attached, can use index finds predicates first pso . if triples have named graphs can add g and, triples have ids i . ag can use index psogi . (from docs: allegrograph triple indices ) an ag triple store created default set of indices. generating specialized indices resource intensive, if know kinds of queries you're going getting, may find worthwhile specify appropriate indices optimize response time...
